#App cannot find the Drone
- 1
Check power and boot
Confirm the ESP8266 controller is actually running.
- 2
Check compiled Wi-Fi credentials
The firmware must match the private network you intend to use.
- 3
Check both devices are on the same network
Phone and controller need local reachability.
- 4
Check network isolation
Guest/client-isolation features can block discovery or local peer traffic.
- 5
Check versions
Use Application v1.0.0 with Firmware v1.0.0 / Protocol 2 for the documented baseline.
- 6
Restart from a clean safe state
Power-cycle while disarmed, reopen the application, and retry discovery.
#Connected but control is unavailable
Verify the correct Drone is connected, the controller is in a safe/valid state, and no other active client is holding the control session. Reconnect from a propeller-off setup before attempting ARM.
